Abstract

The invention discloses a paint dipping technology of insulation paper. The paint dipping technology of the insulation paper includes: step 1, adding insulation paint in a container for mixing paint; step 2, performing drying treatment on an insulation paper base band; step 3, dipping the insulation paper base band after being processed into the insulation paint and then fully dipping the insulation paper base band into the insulation paint, or spraying the insulation paint onto the insulation paper base band and covering the surface of the insulation paper base band; step 4, fetching out the insulation paper base band so as to dry the insulation paper base band through temperature control, and waiting for solidification of the insulation paint and the insulation paper base band. The paint dipping technology of the insulation paper is simple and practical to operate, and the insulation paper base band after processed can be directly used to wrap a conductor and then used as an insulator. Due to the fact that the insulation paint has certain bonding strength, structure of a conductor wrapped by the insulation paper is stable, a coil formed by winding the insulation paper around the conductor does not need paint dipping technology treatment, and production processes are saved.

Description

A kind of paint-dipping process of insulating paper
Technical field
The present invention relates to paint-dipping process technology, especially a kind of paint-dipping process of insulating paper.
Background technology
At present, the not additional any insulating varnish in the surface of existing insulating paper, after insulating paper is wrapped on conductor, in the process of winded coil of transformer, insulating paper can make moist, cause electric property to decline, therefore after coil winding, can be dried it, then coil is immersed to insulating varnish, after insulating varnish is dry, be covered in insulating paper surface, prevent that insulating paper from making moist, guarantee that electric property does not decline, but if the number of plies of the insulating paper of conductor outer wrapping is more, defective tightness, and insulating varnish between layers cannot soak in each layer of insulating paper completely.
Summary of the invention
In order to solve the problems of the technologies described above, the paint-dipping process of a kind of insulating paper provided by the invention, by insulating paper after dipping lacquer is processed, make on insulating paper, with insulating varnish, can be directly used in parcel conductor, guarantee its insulation property, this process is simple, easy to operate, effectively raises the efficiency.
To achieve these goals, the technical solution adopted in the present invention is:
A paint-dipping process for insulating paper, this paint-dipping process step comprises:
Step 1 adds insulating varnish to join paint in container;
Step 2, by the dry processing of insulating paper base band;
Step 3, immerses the insulating paper base band after processing in insulating varnish, and insulating paper base band is fully immersed in insulating varnish; Or insulating varnish is sprayed on and in insulating paper base band, covers its surface;
Step 4, takes out insulating paper base band and dries by temperature control, treats that insulating varnish and insulating paper base band are curing.
In above-mentioned paint-dipping process step, when in described step 3, insulating varnish adopts the operation of spraying method, repeat once or once.
In above-mentioned paint-dipping process step, described insulating varnish is selected solvent-free epoxy resin paint or polyamide paint.
Beneficial effect of the present invention: this paint-dipping process practicality simple to operate, after this paint-dipping process is processed, it is combined with insulating varnish insulating paper, insulating varnish uniformly penetrating is at the internal layer and surface of insulating paper, insulation effect is good, insulating paper after processing can be directly used in and be wrapped on conductor as insulator, because insulating varnish has certain caking ability, makes the structure of insulating paper parcel conductor more stable, conductor is processed without passing through paint-dipping process after turning to coil again, saves production procedure.
Embodiment
The paint-dipping process of a kind of insulating paper provided by the invention, this paint-dipping process step comprises:
Step 1 adds insulating varnish to join paint in container;
Step 2, by the dry processing of insulating paper base band;
Step 3, immerses the insulating paper base band after processing in insulating varnish, and insulating paper base band is fully immersed in insulating varnish; Or insulating varnish is sprayed on and in insulating paper base band, covers its surface;
Step 4, takes out insulating paper base band and dries by temperature control, treats that insulating varnish and insulating paper base band are curing.
In above-mentioned paint-dipping process process, while adopting insulating varnish to be sprayed in insulating paper base band in step 3, this operation repeats once or once, make the dipping lacquer better effects if of insulating paper base band, insulating paper base band can be selected the insulating material of unlike material as required, and its length, width, thickness change according to the different conductor that will wrap up winding, and insulating varnish can be selected different paint materials as required, it is inner and surperficial that it can be dipped in insulating paper base band, and its caking ability can be controlled by temperature.Enumerate following three kinds of embodiment:
Execution mode one: select aramid paper in the present embodiment, thickness 0.05mm, width 15mm, length 5000mm, insulating varnish is selected solvent-free epoxy resin paint, first insulating varnish is formulated to suitable viscosity, by the dry processing of aramid paper, aramid paper after processing immerses in insulating varnish, make aramid paper inside and surface be dipped into desired insulating varnish content, then by controlling temperature, make insulating varnish and aramid paper be cured as inseparable integral body, or also can reach solidification effect after standing a period of time at normal temperatures, insulating paper not moisture-sensitive gas etch at normal temperatures after dipping lacquer is processed, and easy fracture not during wrapped conductor.
Execution mode two: in the present embodiment, select NOMEX-410 paper, thickness 0.05mm, width 18mm, length 6000mm, insulating varnish is selected solvent-free epoxy resin paint, and all the other methods of operation are with execution mode one.
Execution mode three: select NOMEX-410 paper in the present embodiment, thickness 0.05mm, width 18mm, length 6000mm, insulating varnish is selected polyamide paint, first by the dry processing of NOMEX-410 paper, then after insulating varnish being formulated to suitable viscosity, spray on NOMEX-410 paper, for making NOMEX-410 paper inside and surface reach desired insulating varnish content, can carry out once or above repeating spraying, insulating varnish is evenly distributed on paper body.
The insulating paper of processing through dipping lacquer can directly wrap up and being wound on conductor when application, then with this conductor, turn to transformer coil, around rear, good transformer coil is put into drying oven be dried, design temperature size and time as required, after processing, guarantee the fastness boning between insulating paper and conductor and insulating paper and insulating paper, the desired electric property of the equipment that reaches, mechanical performance and insulation property.
The above, be preferred embodiment of the present invention, and the present invention is not limited to the structure of above-mentioned execution mode, as long as it reaches technique effect of the present invention with identical means, all should belong to protection scope of the present invention.
